You will need to provide more information on the model of truck. Is it a BK 3100 or a BL 3600 ? This information will help others who read your post. I've attached a link to a 1947 Truck Shop manual that has a section on the rear axle that may be helpful. I don't know if the 1947 and 1945 Models used the same rear differential or not. Perhaps it will help. I'm sure others with experience will chime in. Best Wishes
